Sajid Javid has abandoned his opposition to allowing Huawei into Britain’s 5G network, with Boris Johnson resisting US pressure to ban the Chinese company.

Mr Javid, when home secretary, was one of five cabinet ministers on the National Security Council (NSC) who effectively prevented Theresa May from giving Huawei the go-ahead last year.

A new NSC, chaired by Mr Johnson, is due to make a final decision about the UK wireless network as soon as a week today, with opinion leaning towards rejecting US demands to ban the company on security grounds. Huawei provides antennae and masts needed for 5G, the fifth generation of wireless networks that will work together to connect everything from laptops and smart fridges to self-driving cars.
